    Awesome light

    Posted by Ted on 21st May 2016

    Great little keychain light. It uses a standard AAA so it's obviously a battery that you can find around the house really really easily. Extremely light weight and very durable. And waterproofing on this light is excellent! 90 lumens is pretty bright for everyday use light. No bunch of modes, just a simple on & off.. which is awesome! It's a twist bezel activation with a great mix between spot & spread.. all in all, an even pattern of light. Olight offers a 5yr warranty for the light. Very affordable. Solid performance. Definitely check this one out and you won't get disappointed!
